Title: Heat reserving hose for painting pipe interior
Inventor: HANEZAWA SHIN
IPC: F16L11/127
Filed: 1988-07-11
Abstract: PURPOSE:To minimize the number of scratches by forming a lot of unevenness extending in the longitudinal direction of the external periphery of a protective coat made of high rigidity polyurethane. CONSTITUTION:An outer protective coat 3 is made of high rigidity and relatively low friction coefficient polyurethane. A lot of unevenness are formed in the longitudinal direction of the external periphery of the protective coat. The head section of a height 3a is formed into a circular arc of curvature R, which allows the protective coat to smoothly slide even if it is brought into contact with the internal wall surface of a pipe. Combined with the reduction of the contact area of the whole, the protective coat is enough slidable even in a bent pipe to be dragged smoothly leaving itself being brought into contact with the internal wall surface of the pipe.

Abstract: PROBLEM TO BE SOLVED: To easily place a sheet original in the case of longitudinal placing by positioning an end of the sheet original in press contact with a press contact face so that the sheet original is not floated from an original placing face when the device is longitudinally placed. SOLUTION: A press contact face 23a whose edge 23 is in press contact with a lower side edge of a sheet original P forms a taper face as a positioning section that is directed in a direction (Z direction) so that the sheet original P is not floated from an original platen glass plate 10 but goes toward the original platen glass plate 10. That is, the press contact face 23a toward the original platen glass plate 10 is tilted downward in the case of longitudinal placing. Since the lower edge of the sheet original P in the case of longitudinal placing goes toward the original platen glass plate 10 on the press contact face 23a by the self-weight of the sheet original P, the sheet original P is set along the original platen glass plate 10, and the sheet original P reaches a state equivalent to that the sheet original P is placed on the original platen glass plate 10 in lateral placing.

Filed: 1998-06-19
Abstract: PROBLEM TO BE SOLVED: To remarkably suppress a decrease in physical properties by heat- treating a powder vulcanized rubber by using a sodium dithionite, sodium hydrogensulfite or mixture thereof. SOLUTION: A recovered powder vulcanized rubber is heat treated by a reducing agent of a sodium dithionite and/or sodium hydrogensulfite to reduce at least a polysulfide bond on a surface of the rubber, thereby generating an SH group. A bond of the rubber blended with a crude rubber becomes rigid by the generation of such a SH group, thereby obtaining a rubber elastic material having god physical properties. As the recovered rubber, a natural rubber NR, diene rubber such as a styrene-butadiene copolymer rubber SBR, polybutadiene BR, ethylene-propylene-diene terpolymer EPDM or the like are vulcanized with sulfur, and then comminuted and recovered, and recovered mainly from a waste tire.
